Description

Die Erfindung bezieht sich auf eine Dichtungsmuffe und ihre Verwendung beim Anschluß von Hausabflußleitungen an die öffentliche Kanalisation.The invention relates to a sealing sleeve and its use in connecting house drain lines to the public sewer system.

Üblicherweise werden Hausabflußleitungen in der Weise verlegt, daß zunächst vom Haus zum Sammler ein Graben ausgehoben wird und die Rohre auf die Grabensohle gelegt werden. Der Anschluß an den Sammler erfolgt durch vorgefertigte Abzweigrohre im Sammler.House drain pipes are usually laid in such a way that first a trench is dug from the house to the collector and the pipes are placed on the bottom of the trench. The connection to the collector is made by prefabricated branch pipes in the collector.

Wird ein Sammler durch Einziehen eines Kunststoffrohres erneuert ("Relining"), so läßt sich dieses Verfahren nur mit Einschränkungen anwenden, weil einerseits umfangreiche Erdarbeiten eingespart werden müssen und andererseits die Abdichtung der Einmündung der Hausabflußleitung in den Sammler schwierig ist.If a collector is replaced by pulling in a plastic pipe ("relining"), this method can only be used with restrictions because, on the one hand, extensive earthworks have to be saved and, on the other hand, sealing the junction of the house drain line in the collector is difficult.

Es bestand die Aufgabe, ein Anschlußverfahren zu finden, welches einfach durchzuführen ist und eine zuverlässige Abdichtung bewirkt.The task was to find a connection method which is simple to carry out and provides a reliable seal.

Es wurde gefunden, daß die Aufgabe gelöst werden kann, wenn eine spezielle Dichtungsmuffe verwendet wird.It has been found that the object can be achieved if a special sealing sleeve is used.

Die Erfindung betrifft somit eine Dichtungsmuffe, bestehend aus einem rohrförmigen, außen zylindrischen Körper, dessen eine Seite durch eine dünne elastische Membrane verschlossen ist, an dessen der Membrane gegenüberliegenden Seite ein nach außen vorspringender Wulst angebracht ist und dessen Innenwand auf einer Länge von Zweidrittel, gemessen von der Wulstseite, der Gesamtlänge der Muffe zylindrisch ist und dann einen Konus bildet, wobei die Wanddicke zur Membrane hin zunimmt und ein Verfahren zu ihrer Anwendung.The invention thus relates to a sealing sleeve, consisting of a tubular, externally cylindrical body, one side of which is closed by a thin elastic membrane, on the side opposite the membrane an outwardly projecting bead is attached and the inner wall of which is measured over a length of two thirds from the bead side, the total length of the sleeve is cylindrical and then forms a cone, the wall thickness increasing towards the membrane and a method of using it.

Die erfindungsgemäße Muffe ist ein rohrförmiger, außen zylindrischer Körper, bei welchem die eine Seite durch eine dünne elastische Membrane verschlossen ist. Auf der der Membrane gegenüberliegenden Seite ist der Rand mit einem nach außen vorspringenden Wulst versehen. Die innere Wand ist im oberen Bereich ebenfalls zylindrisch, im unteren Teil jedoch konisch ausgebildet. Die Wandstärke nimmt ab ca. 2/3 der Wandlänge von der Wulstseite her zur verschlossenen Seite hin zu. Der zylindrische Teil der Innenwand hat somit eine Länge von vorzugsweise Zweidrittel der Gesamtlänge der Muffe, gemessen von der Wulstseite.The sleeve according to the invention is a tubular, externally cylindrical body, in which one side is closed by a thin elastic membrane. On the side opposite the membrane, the edge is provided with a bulge projecting outwards. The inner wall is also cylindrical in the upper area, but conical in the lower part. The wall thickness increases from about 2/3 of the wall length from the bead side to the closed side. The cylindrical part of the inner wall thus has a length of preferably two thirds of the total length of the sleeve, measured from the bead side.

Die Größe der Dichtungsmuffe richtet sich nach den Durchmessern der zu verbindenden Rohre. Dabei ist die lichte Weite der Dichtungsmuffe abhängig vom Durchmesser der Hausabflußleitung und die Länge der Muffe abhängig vom Durchmesser - und der dadurch vorgegebenen Wandstärke - des Sammlers. Befindet sich beispielsweise in einem Steinzeugsammler ein Reliningrohr aus Kunststoff, so ist die Dichtungsmuffe besonders lang. Die Wandstärke der Muffe an der Wulstseite beträgt 9 bis 10 % der lichten Weite und nimmt zum verschlossenen Ende hin um 20 bis 30 %, vorzugsweise 25 % zu. Die Höhe und die Breite des Wulstes betragen 5 bis 15 %, bezogen auf die lichte Weite. Die Verschlußmembrane ist 0,2 bis 1,0 mm dick, abhängig vom Material, aus welchem die Muffe besteht.The size of the sealing sleeve depends on the diameter of the pipes to be connected. The clear width of the sealing sleeve is dependent on the diameter of the house drain line and the length of the sleeve is dependent on the diameter - and the resulting wall thickness - of the collector. For example, if there is a plastic relining pipe in a stoneware collector, the sealing sleeve is particularly long. The wall thickness of the sleeve on the bead side is 9 to 10% of the clear width and increases by 20 to 30%, preferably 25%, towards the closed end. The height and width of the bead are 5 to 15%, based on the clear width. The sealing membrane is 0.2 to 1.0 mm thick, depending on the material from which the sleeve is made.

Die erfindungsgemäße Dichtungsmuffe besteht aus einem gummielastischen Material, beispielsweise Polychloropren.The sealing sleeve according to the invention consists of a rubber-elastic material, for example polychloroprene.

Eine bevorzugte Dichtungsmuffe für eine Hausabflußleitung aus einem 180 mm dicken Rohr aus Polyethylen hat folgende Abmessungen: Lichte Weite an der Wulstseite 180 mm Lichte Weite an der verschlossenen Seite 172 mm Wandstärke 16 bzw. 20 mm Höhe des Wulstes 10 mm Breite des Wulstes 10 mm Gesamte Länge 150 mm Dicke der Abschlußmembrane 0,5 mm A preferred sealing sleeve for a house drain pipe made of a 180 mm thick pipe made of polyethylene has the following dimensions: Clear width on the bead side 180 mm Clear width on the closed side 172 mm Wall thickness 16 or 20 mm Bead height 10 mm Bead width 10 mm Whole length 150 mm Closing membrane thickness 0.5 mm

Die Dichtungsmuffe ist für Rohre aus konventionellen Materialien, in denen ein Reliningrohr liegt, vorgesehen.The sealing sleeve is intended for pipes made of conventional materials in which a relining pipe is located.

Das Verfahren zur Anwendung der erfindungsgemäßen Dichtungsmuffe wird in der Weise durchgeführt, daß das Hausabflußrohr an dem dem Sammler zugewandten Ende auf der Außenseite zu einem Konus abgeschrägt wird, wobei die Länge und der Winkel des Konus mit den entsprechenden Abmessungen in der Muffe übereinstimmen. Danach wird das Rohrende bis zum Anschlag an der Abschlußmembrane in die Dichtungsmuffe eingeführt. Sodann wird von einer an einer geeigneten Stelle ausgehobenen Grube - falls der Sammler nicht begehbar ist - zum Sammler hin - oder vom Sammler - falls der Sammler begehbar ist - zum Haus hin eine zielgenaue Bohrung vorangetrieben. Der Durchmesser dieser Bohrung entspricht im Erdreich mindestens dem Gesamtdurchmesser der Dichtungsmuffe, in der Wand des Sammlers jedoch dem Durchmesser des zylindrischen Teils der Muffe. Das Hausabflußrohr wird nunmehr - Muffe voran - vom Haus her durch die Bohrung geschoben, bis die Muffe mit dem Wulst an der Außenseite der Wand des Sammlers anliegt. Beim Weiterschieben des Rohres wird die Abschlußmembrane durchstoßen. Gleichzeitig bewirken die konischen Flächen von Rohr und Muffe, daß die Muffe aufgetrieben und fest gegen die Wandung der Bohrung in der Wand des Sammlers gepreßt wird. Das Muffenmaterial bildet einen ringsumlaufenden Dichtwulst. Das in den Sammler hineinragende konische Rohrende wird in einem ausreichenden Abstand von der Kanalinnenwand - bei nicht begehbarem Kanal mittels eines Schneidroboters - abgeschnitten.The method for using the sealing sleeve according to the invention is carried out in such a way that the house drain pipe is chamfered on the outside to a cone at the end facing the collector, the length and angle of the cone corresponding to the corresponding dimensions in the sleeve. The pipe end is then inserted into the sealing sleeve as far as it will go on the end membrane. Then, from a pit dug in a suitable place - if the collector is not accessible - towards the collector - or from the collector - if the collector is accessible - towards the house, a well is drilled. The diameter of this hole corresponds at least to the total diameter of the sealing sleeve in the ground, but in the collector wall to the diameter of the cylindrical part of the sleeve. The house drain pipe is now - sleeve first - pushed from the house through the hole until the sleeve with the bead rests on the outside of the collector wall. When the tube is pushed further, the end membrane is pierced. At the same time, the conical surfaces of the pipe and sleeve cause the sleeve to be distended and pressed firmly against the wall of the bore in the collector wall. The sleeve material forms an all-round sealing bead. That in the collector The protruding conical pipe end is cut off at a sufficient distance from the inner wall of the duct - if the duct is not accessible using a cutting robot.

Die Figuren zeigen eine erfindungsgemäße Dichtungsmuffe (Figur 1) und die Vorgänge bei ihrer Anwendung (Figur 2).The figures show a sealing sleeve according to the invention (Figure 1) and the processes in its application (Figure 2).

Die Muffe (1) gemäß Figur 1 hat eine glatte zylindrische Außenwand (2) und eine im oberen Bereich ebenfalls zylindrische und im unteren Drittel konische Innenwand (3). Am oberen Rand schließt die Muffe (1) mit einem Wulst (4) ab, während sie unten durch eine Abschlußmembrane (5) verschlossen ist.The sleeve (1) according to FIG. 1 has a smooth cylindrical outer wall (2) and an inner wall (3) which is also cylindrical in the upper area and conical in the lower third. The sleeve (1) closes at the top with a bead (4), while it is closed at the bottom by a closing membrane (5).

Figur 2 zeigt den Anschluß einer Hausabflußleitung an einen sanierten, d.h. einen ein eingezogenes Kunststoffrohr enthaltenden Sammelkanal. Auf der linken Seite der Figur wurde das Hausabflußrohr (6), welches am vorderen Ende mit einem Konus (7) versehen ist, bis zum Anschlag an der Abschlußmembrane (5) in die Muffe (1) hineingeschoben. Hausabflußrohr (6) und Muffe (1) wurden soweit durch das Sammlerrohr (8) und das Kunststoffrohr (Reliner) (9) geführt, bis der Wulst (4) fest am Sammlerrohr (8) anliegt. Auf der rechten Seite der Figur ist das Hausablußrohr (6) durch die Muffe (1) hindurchgeschoben worden, sodaß diese fest gegen das Rohr (9) gepreßt wurde und den Wulst (10) bildet. Die überstehenden Enden von Rohr (6) und Muffe (1) wurden bereits abgeschnitten.Figure 2 shows the connection of a house drain pipe to a renovated, i.e. a collecting duct containing a retracted plastic pipe. On the left side of the figure, the house drain pipe (6), which is provided with a cone (7) at the front end, was pushed into the sleeve (1) up to the stop on the end membrane (5). The house drain pipe (6) and sleeve (1) were passed through the collector pipe (8) and the plastic pipe (reliner) (9) until the bead (4) was tight against the collector pipe (8). On the right side of the figure, the house drain pipe (6) has been pushed through the sleeve (1) so that it has been pressed firmly against the pipe (9) and forms the bead (10). The protruding ends of pipe (6) and sleeve (1) have already been cut off.

Die erfindungsgemäße Dichtungsmuffe bewirkt eine feuchtigkeits- und chemikalienbeständige Abdichtung zwischen dem Hausabflußrohr und dem Sammelkanalrohr. Die Verbindung ist etwas elastisch und kann daher eventuelle geringe Setzungen und Verschiebungen auffangen. Die Anwendung der Muffe ist einfach, so daß sichere Einbauergebnisse zu erwarten sind. Dabei bringt die Abschlußmembrane die Vorteile, daß sie als Anschlag für das Hausabflußrohr dienen kann und außerdem während der Montage kein Schmutz in die Hausabflußleitung geraten kann. Die erfindungsgemäße Dichtungsmuffe ermöglicht eine Sanierung defekter Hausabflußleitungen ohne umfangreiche offene Erdarbeiten.The sealing sleeve according to the invention brings about a moisture and chemical resistant seal between the house drain pipe and the collecting sewer pipe. The connection is somewhat elastic and can therefore absorb any small settlements and displacements. The application of the sleeve is simple, so that it is safe Installation results are expected. The end membrane has the advantages that it can serve as a stop for the house drain pipe and also that no dirt can get into the house drain line during installation. The sealing sleeve according to the invention enables refurbishment of defective house drain lines without extensive open earthwork.
